bug#25353: Shell-script[bash] mode not ready for extglob

[積丹尼 Dan Jacobson]

Doing
 C-x h [mark-whole-buffer]
 <tab> [indent-for-tab-command]
just makes indentation out of whack, here where we use shopt -s extglob
patterns. emacs-version "25.1.1".


#!/bin/sh
b=256 t=10000
shopt -s extglob
while read cid
do
    echo -n "$cid: "
    case $cid in
        +([0-9])-[0-9][0-9])
                            printf "%d\n" $((${cid%-*} * 256 + ${cid#*-}))
                            for i in 01 11 21 31 41 51
                            do printf "%d %s\n" $((${cid%-*} * 256 + i)) $i
                            done
                            ;;
                            +([0-9]))
                                     printf "%06d-%02d\n" $((cid / b)) $((cid % 
b))
                                     printf "%02d-%04d-%02d\n" $((cid / b / t)) 
 $((cid / b % t)) $((cid % b))
                                     ;;
                                     *) echo '???' 1>&2; exit 11;
                                        ;;
                                     esac
